Toallwhmnitmaycomem: Be it known that I, Oman-s M. DU M N '1' citizen of the United States of America, "and a resident of Cedar Falls, Blackhawk 3 specification.

My invention relates to improvements in washing machines, and the object of my improvement is to provide an nnproved and efficient mechanism for actuating the plunger-head contained in the tub of the 'machine. This object Ihave accomplished by the mechanism which is hereinafter described and claimed, and in the accompanyiif drawing, in which: I

Figure 1 is a si e proved washing machine, with a part of the tub and cover broken or sectioned away, and with dotted lines showing the raised position of the cover and mechamsm mountedthercon. Fig.2isatopplanviewofsa1d machine.

Similar numerals of reference denote corresponding parts throughout the several views.

The tub 17 has a. cover 16 adapted to swing on the hinges 18,, and a center beanng 1s placedinanorificeinsaldeovertoseata vertical plunger-rod 1, the latter adapted to bothrcmprocateandrockwithmthebearing to impart like motions to the plungerhead2withinthetub. Thebearingforms aninlpartofacastingflfixedly' moun H on said cover, and having an right 15 whose upper end is bent late y and orificed to seat the upper end of said plunger-rod. Said casting also has the alined horizontal 12 and 18 in which is rotatabl seated a horizontal rotatable shaft 11. e inner end of said shaft 11 is provided with a crank 10 havmg a fixed crank-pin, the latter transversely orificed to seat rotatabiy a pin 9, and one end of a cylindrical pin 6 is pivoted on a pintle 7 connecting the forks 8 of said pin '9. The vertical plunger-rod 1 has a transverse orifice in which the other end of the pin 6 is both slidably and rotatably Ontheouterend oftheshaftll isfixedly mounted a gear-wheel 22 in mesh with another gear-wheel 23, the latter rotatably mounted on a stub-shaft 27 pro ected from saidcasting 14.

is mounted on said tub, and has a projecting stub-shaft 33 on which is rotatably mounted a fixedly connected pinion 24 and a fly-wheel 34. The numeral 32 denotes a hand-lever which is pivoted at its lower end where incased in a socket casting 31 on a stub-shaft 36 projected from-said castmg 21. A pitman 28 has one end pivoted to a pmtle 35 on a lug 29 of the socket 31, while its other end is curved downwardly and pivoted on a 27 projected from the arwheel 23. e cover 16 has a latch 19 adaipted to b -.i|;: Ly a catch 20 on the tub, tolseryveiuasbsgparablifa f means.

t seen, re e to 1, that the dottedlines iiidicat t l ie raised' i iosi- 'tion'of'the cover withthe gear-wheels 22 and 23 mounted thereon, and that although the said cover swings up and down in the usual way, that the said gears simply ride radially about the pinion 24 without becoming out of mesh with each other and Without in any way interfering with the actions of the mechanism. This is due to the fact that the pinion 24 and fly-wheel 34 so mounted on the tub that their axis is alined with the hinged connection of the cover. The lever 32 when reciprocated, rotates said gears, with the shaft 11, the crank 10 and pins 9 and 6, causing the plunger-rod 1 to have a spiral motion, being a compounded motion of reciprocation and rotarv movements, a s the pin 6 both slides and rotates in in the orifice in said rod 1. The mechanism shown therefore is always in working condition, whether the cover is raised or low- Having described my invention, what I claim as new, and desire to secure by Letters Patent, is:

1. The combination with a relatively fixed support, a body hinged thereto, a coaxially connected fly-wheel and pinion rotatably mounted on the support in line with the hinged joint of the body, a gear-wheel rotatably mounted on the body and in mesh with said pinion, a rotatable shaft mounted on said body, a gear-wheel fixed on said shaft and in mesh with said first-mentioned gear-wheel, a crank on said sha a bifurcated in rotatably mounted in e crankpin 0 said crank, a reciprocatory alternatin rotary-shaft mounted in said body, said aft having a transverse orifice and a pin mounted in said orifice for both shding and rocking movements, one end of said pin being pivoted between the forks of said bifurcated pin.
